Last week, production started on Marvel's second Phase Three adventure Doctor Strange in Nepal. While several of the main cast members have already been announced, The Wrap reports that Transparent actress Amy Landecker has signed on for a mysterious role. It isn't known if she has already started filming in Nepal, or how large a role she may have in the production.

Regardless of who she is playing, Amy Landecker joins a cast that includes Benedict Cumberbatch as Doctor Strange, Tilda Swinton as The Ancient One, Chiwetel Ejiofor as Baron Mordo and Michael Stuhlbarg as Nicodemus West. Rachel McAdams has been confirmed as the female lead, who has been rumored to be the Night Nurse. Marvel hasn't released an official synopsis yet, but producer Kevin Feige did confirm that the Doctor's origin story will be told, after rumors surfaced that the movie would open with Strange established as the Sorcerer Supreme.

The original comics follow Dr. Stephen Strange, a neurosurgeon who loses everything after a car accident leaves both his hands injured, rendering him unable to perform surgery. This leads the Doctor to travel the world in search of a cure for his hands, where he meets The Ancient One, who takes Stephen under her wing. The Ancient One trains him to defend the world against evil on his way to becoming the Sorcerer Supreme.

Scott Derrickson (Deliver Us from Evil and Sinister) is directing from a script by Jon Spaihts, the writer behind Prometheus and upcoming projects such as Universal's Untitled Mummy Reboot and Sony's Passengers, starring Jennifer Lawrence and Chris Pratt. Marvel has already set a November 4, 2016 release date for Doctor Strange, arriving almost exactly six months after Captain America: Civil War.

Amy Landecker is best known for her portrayal of Sarah Pfefferman on Amazon Studios' breakthrough hit series Transparent. Doctor Strange also reunites the actress with Michael Stuhlbarg, who both starred in the 2009 Best Picture nominee A Serious Man. She recently starred in this year's Project Almanac and has another film called The Meddler awaiting release, which stars Rose Byrne, Susan Sarandon and J.K. Simmons.
